Ventolin is indicated for the relief and prevention of airway obstruction (bronchospasm) in patients with asthma and in patients with exercise-induced asthma. Ventolin can also be used in treating patients with emphysema and chronic bronchitis when their symptoms are related to reversible airway obstruction.

Ventolin works by relaxing the smooth muscle in the airway, which allows air to flow in and out of the lungs more easily.

The inhaled form of Ventolin starts working within 15 minutes and can last up to 6 hours.

Ventolin is currently available as Asthalin brand manufactured by Cipla.
